Browser porn modes exposed as useless

The private modes on many current browsers are close to useless according to a study conducted by Stanford University.

Commonly known as 'Porn Mode' because it is most often used when users are doing a bit of surreptitious one-handed surfing, most modern browsers have some kind of private browsing setting which is supposed to leave behind no trace of whatever disgraceful filth you have been drooling over while you were supposed to be writing that report.

Private browsing is supposed to permanently erase things like cookies and history registries which could point to nefarious activities - like planning a secret gift for your wife according to the TV ads - as well as the browser's cache.

But the boffins at Stanford have discovered that other ways in which the browser gathers data were left intact especially when visiting secure sites, or when certain plug-ins or add-ons were installed.

Dan Boneh [oh come on...] from Stanford University told the BBC that adding extras to browsers like Firefox, Internet Explorer, Chrome and Safari could "completely undermine" the anonymity of so called Private Browsing.
